Remove personal electronic devices larger than a cell phone from your carry-on bag and place them into a bin with nothing placed on or under them for X-ray screening. (E.g. laptops, tablets, e-readers and handheld game consoles.) Remember to check the bins and collect all belongings after going through screening.

The requirement to remove items from your carry-on bag is currently in a state of transition due to the rollout of new security technology. Historically, passengers have been required to remove all large electronics (laptops, tablets) and their quart-sized bag of liquids. However, many major airports—particularly in the UK and some hubs in the US—are installing advanced CT (Computed Tomography) scanners. At airports where these new scanners are fully operational, such as London Heathrow, Birmingham, or Edinburgh, you can now leave your liquids (up to 2 liters) and all electronics inside your bag. At airports that have not yet upgraded, the old rules still apply: you must place laptops, large cameras, and your clear plastic bag of liquids (100ml limit) in separate bins. Because the rules vary by specific terminal and airport, the best practice is to watch for signage at the security entrance or follow the direct instructions of the security officers. Always be prepared to remove items just in case the specific lane you are in uses older technology.
